Photosynthesis is usually explained as the reverse of cellular respiration. Respiration smashes down complicated molecules to produce energy that is employed to make ATP. Photosynthesis takes energy through photons and utilizes it to build complicated molecules. However both systems make use of associated proton pump and an electron transport chain and ATP synthase like a key part of the procedure.
In photosynthesis electrons get into the transport chain after receiving light energy in respiration the electrons are given by organic food molecules. In both instances the electron carry chain uses the energy to pump hydrogen ions around a membrane. The protons pass back via ATP synthase, driving the creation of ATP. In photosynthesis this ATP is employed to construct organic molecules from water and carbon dioxide.
Cellular respiration is the procedure of oxidising food molecules or breaking down chemical bonds of glucose into water and carbon dioxide. The energy introduced in the procedure is trapped in the type of ATP and used by various energy consuming routines of the cell. It is a pair of metabolic reactions which unlike photosynthesis which takes place in the chloroplast, cellular respiration occurs in the mitochondria.
The whole breakdown of glucose into water and carbon dioxide requires two main steps: aerobic and glycolysis respiration. Aerobic respiration is the process where the pyruvate molecules made by glycolysis goes through further breakdown in the existence of oxygen and produces thirty four molecules of ATP. Glycolysis is the anaerobic catabolism of glucose that takes place in all the cells and creates two molecules of ATP.
Photosynthesis is the process employed by plant cells to change light energy from sunlight into chemical energy, in order to create energy-rich carbohydrate molecules such as glucose. Cellular respiration is the procedure of breaking down food molecules to have energy and store it in the type of adenosine triphosphate (ATP) molecules. Therefore photosynthesis is to chloroplasts as cellular respiration is to mitochondria.Plant cells, after making sugar molecules via photosynthesis, go through cellular respiration to generate ATP molecules. Animals get food molecules through plants and other organisms and then go through cellular respiration to have ATP molecules. All living organisms make use of these stored ATP molecules to perform their metabolic processes.
